ALFRED ANDERSON, OF ROCKFORD, ILLINOIS, ASSIGNOR '10 SCI-IUMANN PIANOCOMPANY, OF ROCKFORD, ILLINOIS, A CORPORATION OF ILLINOIS.

PEDAL FOR PIANOS.

To all whom it may concern:

Be it known that I, ALFRED ANDERSON, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Pedals for Pianos,of which the following is a specification.

The object of this invention is to form a connection between a pedal andits rocking rod.

In the accompanying drawings, Figure 1 is a section on line a a Fig. 2,the pedals being shown in plan. Fig. 2 is a section on line b b Fig. 1.Fig. 3 is a section on line 0 c Fig. 1.

To the base 1 of the piano case are secured three brackets 2, 3 and 4:having upturned perforated ears 5. Pedals 6, 7 and 8 are pivotallyconnected to the ears 5 of the brackets 2, 3 and 4 respectively. Thepedals are each provided with a series of holes 9. A spring 10 islocated beneath each of the pedals 6, 7 and S, the action being to holdthe pedals elevated against the cushioned stops 11. On the base 1 of thepiano case are pivotally mounted two rocking bars 12 and 13 by means ofthe cleats 14, such bars being disposed at an angle to the pivotal axisof said pedals. To the rocking bar 12 are rigidly secured twooverhanging arms 15 and 16, and to the rocking bar 13 is rigidly securedan overhanging arm 17. These arms 15, 16 and 17 have their free endslocated over the pedals 6, 7 and 8 respectively, and rods 18 are locatedin the holes 9 of the pedals with their headed end against the underfaceof the pedal. The upper ends of these rods are screw-threaded andreceive thumb-nuts 19. These rods form a connection between the pedalsand the 0verhanging arms, and the distance between the arms and pedalsis variable by turning the thumb-nuts. To the rocking bar 12 isconnected an arm 20, and to the rocking rod 13 Specification of LettersPatent.

is connected an arm 21. Rods 22 and 23 are supported by the arms 20 and21 respectively. By depressing the pedal 8, the rod 23 will be elevatedin the usual manner, and by depressing the pedals-6 and 7 the rod 22will be elevated, but the pedal 6 will raise the rod 22 farther than thepedal 7 by reason of the rod 18 being located a greater distance fromthe hinge of the pedal 6 than the rod of the pedal 7, such difference indistance being due to the angular relation of the rod 12. By means ofthe thumb-nuts, the rods 22 and 23 can be adjusted.

I claim as my invention- 1. In a piano, the combination with a pedal,and means for pivotally supporting the same, of a rock shaft mountedadjacent thereto, an arm rigidly secured to said shaft and overhangingsaid pedal, and means adjustably connecting the free end of said. armwith said pedal.

2. In a piano, the combination with a pedal, and means for pivotallysupporting the same, of a rock shaft mounted adj acent thereto, an armrigidly secured to said shaft and overhanging said pedal, and meansadjustably connecting the free end of said arm with said pedallengthwise of the pedal.

3. In a piano, the combination with a pair of pedals, of means forpivot-ally supporting said pedals for movement about a common aXis, of arock shaft mounted adjacent said pedals at an angle to said aXis, a pairof arms each rigidly secured to said shaft and overhanging one of saidpedals, and means connecting the free end of each of said arms with itsrespective pedal.

In testimony whereof I have hereunto set' my hand in presence of twosubscribing witnesses.
